PROBABILISTIC HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE LA CROSSE WI
930 AM CST THU FEB 21 2013

       ...FIRST SPRING HYDROLOGIC SUMMARY AND OUTLOOK...

THE FOLLOWING INFORMATION IS THE FIRST OF TWO PLANNED FLOOD OUTLOOKS
PROVIDING FLOOD POTENTIAL AND CLIMATOLOGICAL INFORMATION FOR THIS COMING
SPRING. THIS OUTLOOK CONTAINS INFORMATION WHICH WAS COLLECTED FROM A 
NUMBER OF SOURCES...INCLUDING THE UNITED STATES GEOLOGICAL SURVEY /USGS/...
US ARMY CORPS OF ENGINEERS /USACE/...MIDWEST REGIONAL CLIMATE CENTER /MRCC/...
CLIMATE PREDICTION CENTER /CPC/...US DROUGHT MONITOR...AND THE NATIONAL OPERATIONAL REMOTE SENSING CENTER /NOHRSC/. THE FOLLOWING OUTLOOK IS A SUMMARY OF THE PAST AND PRESENT BASIN CONDITIONS FOR PORTIONS OF NORTHEAST IOWA...SOUTHEAST MINNESOTA... AND SOUTHWEST INTO CENTRAL WISCONSIN. *** FLOOD POTENTIAL HIGHLIGHTS *** IN SHORT...THE FLOODING POTENTIAL FOR THIS COMING SPRING APPEARS TO BE NORMAL TO SLIGHTLY BELOW NORMAL. GIVEN THE CURRENT CONDITIONS...THE OVERALL RISK OF FLOODING IS NEAR NORMAL...OR PERHAPS SLIGHTLY LESS THAN NORMAL. HOWEVER...THERE ARE SOME FACTORS THAT COULD STILL CONTRIBUTE TO AN INCREASE IN THE FLOODING POTENTIAL AS WE MOVE CLOSER TO SPRING. THE FROST CONDITION IS OF MOST CONCERN. THE FROST DEPTH IS QUITE DEEP...FROM 15 TO 30 INCHES ACROSS THE REGION. IN ADDITION...THE TOP SEVERAL INCHES OF SOIL ARE COMPLETELY FROZEN...AS RAINFALL AND THE SNOW MELT FROM EARLY JANUARY WAS LOCKED INTO THE SOIL PRIOR TO GETTING ANY APPRECIABLE SNOW COVER. THIS ICY SOIL CONDITION... SOMETIMES REFERRED TO AS CONCRETE FROST...SHOULD LEAD TO INCREASED RUNOFF INTO CREEKS AND RIVERS AS THE SNOWMELT PERIOD BEGINS. ANY MELT WATER WILL BE UNABLE TO PENETRATE THE FROZEN GROUND...AND WILL DIRECTLY RUN OFF INTO RIVERS AND CREEKS...EVEN MORESO THAN IN A NORMAL SPRING. IN ADDITION...THERE ARE A COUPLE OF WINTER STORM SYSTEMS DUE TO IMPACT THE AREA OVER THE NEXT WEEK...AND THIS WILL LIKELY ADD TO THE SNOW COVER AND AVAILABLE MOISTURE FOR FUTURE RUNOFF. THE NEXT OUTLOOKS ISSUED ON MARCH 7TH WILL BE ABLE TO BETTER CAPTURE THE EFFECTS OF THESE STORMS. *** FLOOD POTENTIAL *** IN TABLE 1 BELOW, THE CURRENT (CS) AND HISTORICAL (HS) OR NORMAL PROBABILITIES OF EXCEEDING MINOR...MODERATE...AND MAJOR FLOOD STAGES ARE LISTED FOR THE VALID TIME PERIOD. CS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY BASED ON CURRENT CONDITIONS. HS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY BASED ON HISTORICAL OR NORMAL CONDITIONS. WHEN THE VALUE OF CS IS GREATER THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS HIGHER THAN NORMAL. WHEN THE VALUE OF CS IS LESS THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS LOWER THAN NORMAL. ...TABLE 1--PROBABILITIES FOR MINOR...MODERATE AND MAJOR FLOODING...

THIS DROUGHT DEVELOPED RAPIDLY IN JUNE AND JULY OF 2012. TEMPERATURES DURING THIS TIME PERIOD AVERAGED 4 TO 5 DEGREES ABOVE NORMAL AND PRECIPITATION DEFICITS RANGED FROM 3 TO 8 INCHES ALONG AND SOUTH OF THE INTERSTATE 90 CORRIDOR. THIS DROUGHT THEN EXPANDED INTO NORTH-CENTRAL WISCONSIN AS 3 TO 9 INCH PRECIPITATION DEFICITS DEVELOPED ACROSS THAT AREA. BASED ON THE PALMER DROUGHT SEVERITY INDEX...THIS DROUGHT RANKS AS THE 15TH WORST SINCE 1890 FOR THE LA CROSSE HYDROLOGICAL SERVICE AREA. IT WAS THE MOST SEVERE SINCE THE 1987-89 DROUGHT /WHICH RANKS AS THE MOST SEVERE FOR THE AREA/. DESPITE HEAVY RAINS ON OCTOBER 13-14...OCTOBER 24-25...AND NOVEMBER 11 /MAINLY SOUTHEAST OF A CHARLES CITY IA TO WAUSAU WISCONSIN LINE/...PRECIPITATION DEFICITS GREW ANOTHER 1 TO 4 INCHES DURING THE AUTUMN. BY THE END OF NOVEMBER...THE JUNE TO NOVEMBER PRECIPITATION DEFICITS RANGED FROM 8 TO 13 INCHES ACROSS NORTHEAST IOWA...FROM 4 TO 12 INCHES ACROSS SOUTHEAST MINNESOTA...AND FROM 3 TO 11 INCHES ACROSS WESTERN WISCONSIN. DURING THE WINTER OF 2012-13...ABOVE-NORMAL PRECIPITATION HAS ACTUALLY FALLEN ACROSS THE AREA. THE PRECIPITATION SURPLUSES WERE UP TO AN INCH ACROSS SOUTHEAST MINNESOTA AND MUCH OF NORTHEAST IOWA...AND 1 TO 4 INCHES ACROSS CLAYTON...FAYETTE...AND ALLAMAKEE COUNTIES IN NORTHEAST IOWA AND ACROSS WESTERN WISCONSIN. DESPITE THESE ABOVE NORMAL PRECIPITATION TOTALS...ONLY A SMALL FRACTION OF THIS MOISTURE HAS ACTUALLY MADE IT INTO THE SOILS DUE TO THE WAY THAT THE FROST DEVELOPED THIS WINTER. A FEW EARLY WINTER RAIN...ICE AND SNOWMELT CYCLES COMBINED WITH COLD TEMPERATURES ACROSS THE AREA...HAVE CONTRIBUTED TO DEEP FROZEN SOILS THAT MAY ACTUALLY INTERFERE WITH THE INFILTRATION AND ABSORPTION OF SNOWMELT RUNOFF INTO THE SOILS. FROST DEPTHS ARE QUITE DEEP RUNNING AN AVERAGE OF 15 TO 30 INCHES ACROSS THE AREA AND THIS FROZEN GROUND WILL BE A FACTOR IN THE MAGNITUDE AND TIMING OF SPRING RUNOFF. THE TOP LAYER OF THE SOIL HAS A "CONCRETE FROST" WITH THE TOP SEVERAL INCHES OF THE SOIL COMPLETELY FROZEN WITH ICE. AS OF TODAY...THE SNOWPACK IS FAIRLY SHALLOW FOR MUCH OF THE BASINS...BUT ADDITIONAL STORMS IN THE COMING WEEK LOOKS TO INCREASE THE AMOUNT OF SNOW ON THE LANDSCAPE. IN NORTHEAST IOWA...CURRENT SNOW WATER EQUIVALENTS ARE LESS THAN A HALF-INCH...WITH THE AVERAGE SNOW DEPTH AT 2 INCHES OR LESS. IN SOUTHEAST MINNESOTA...CURRENT SNOW DEPTH IS 3 INCHES OR LESS...WITH WATER EQUIVALENT AMOUNTS OF LESS THAN 1 INCH. FINALLY IN WISCONSIN...THE SNOW DEPTH RANGES FROM JUST A FEW INCHES IN SOME PLACES ALONG THE MISSISSIPPI RIVER COUNTIES...TO AS MUCH AS 4 TO 8 INCHES FROM RICHLAND AND MONROE COUNTIES UP TOWARD CLARK COUNTY. SOME ISOLATED AMOUNTS OF 10 TO 12 INCHES ARE SEEN OVER CENTRAL AND NORTH-CENTRAL WISCONSIN. SNOW WATER EQUIVALENT AMOUNTS IN THESE AREAS RANGE FROM AN INCH OR LESS ALONG THE RIVER...TO AS MUCH AS 2 OR 3 INCHES IN CENTRAL AND NORTH-CENTRAL WISCONSIN. AS ALWAYS...ICE JAM FLOODING IS POSSIBLE DURING THE SPRING MELT PERIOD. A FAIRLY WET LATE JANUARY AND EARLY FEBRUARY ACROSS THE UPPER MISSISSIPPI RIVER BASIN AND ITS TRIBUTARIES HAS THE RIVERS RUNNING AT FAIRLY NORMAL LEVELS. HOWEVER THE LONG-TERM DROUGHT REMAINS IN PLACE AND AND RIVER CONDITIONS COULD RECEDE QUICKLY BACK TO LOW CONDITIONS AFTER THE SNOWMELT RUNOFF SEASON. IN ADDITION...THE WATER TEMPERATURES ACROSS THE NORTHERN HEMISPHERE/S PACIFIC BASIN ARE FAVORABLE FOR INCREASED PROBABILITIES OF ABOVE-NORMAL PRECIPITATION DURING BOTH MARCH AND THE SPRING. THIS COULD HAVE AN IMPACT ON THE FLOODING SITUATION ACROSS THE AREA AS WELL. *** LONG RANGE FLOOD POTENTIAL OUTLOOK *** THE OUTLOOK IN TABLE 2 BELOW WILL SHOW THE PROBABILITY FOR FLOODING AT SEVERAL LOCATIONS AROUND THE REGION. THIS OUTLOOK PROVIDES LONG-RANGE PROBABILISTIC RIVER OUTLOOKS FOR RIVER BASINS IN PARTS OF SOUTHEAST MINNESOTA...NORTHEAST IOWA...AND SOUTHWEST WISCONSIN. THIS OUTLOOK IS DIVIDED INTO TWO PARTS...ONE FOR HIGH WATER...AND ONE FOR LOW WATER.
